Grýla
From a relatively young age Icelandic children are told the story of Grýla, the ogress living in the Icelandic mountains. She is a dreadful character, described as part troll and part animal and the mother of 13 precocious boys (the Yule Lads). Grýla lives in the mountains with her third husband, her thirteen children and a black cat. Every Christmas, Grýla and her sons come down from the mountains: Grýla in search of naughty children to boil in her cauldron and the boys in search of mischief. She can only capture children who misbehave but those who repent must be released.

The Yule Lads
Icelandic children place a shoe in their bedroom window each evening in the 13 days before Christmas. Every night one Yuletide lad visits, leaving sweets and small gifts or rotting potatoes, depending on how that particular child has behaved on the preceding day. Each Yuletide lad has a specific idiosyncrasy and will therefore behave in a particular manner.

The Christmas Cat
Old Icelandic folklore states that every Icelander must receive a new piece of clothing for Christmas or they will find themselves in mortal danger. An enormous black cat prowls Iceland on Christmas Eve and eats anyone who doesn’t follow this simple rule. This obnoxious feline is know as the Christmas Cat.
